SILVERADO DASH LIGHTS

2003 Chevrolet Truck

How do I replace the dash/instrument light bulbs in my 2003 Chevy Silverado? The A/C temperature slider light is burned out. My local Chevy dealer says the lights are not replaceable and I must replace the entire A/C dash module at $160. This seems ridiculous.

Update: I removed and disassembled the A/C instrument pod. The light bulbs are soldered to a PC board. If I wiggled the (tiny) light socket, the bulb lights up intermittently. The solder points are good, so I assume the bad connection is in the socket, which is not repairable. Does anyone out there have a 2003 Silverado instrument diagram with the bulb spec for the A/C module? I plan to solder in new bulbs.
